3.1 Pre-Cleaning Sampling and Testing

Prior to any cleaning and pumping operations, the contractor shall perform appropriate tests of the OWS contents (including floating materials, liquids, and sludge) to determine if the materials meet the criteria for hazardous waste.

• Hazardous Contingency: If tests indicate the presence of hazardous materials, the contractor shall immediately terminate servicing and contact the COR and the installation environmental office. The environmental office will determine the subsequent requirements for the disposal of hazardous contents.

3.2 Pumping, Evacuation, and Packaging

If the contents are confirmed as non-hazardous, the contractor shall proceed with the cleaning operations. The contractor shall pump all oil, oil residue, sludge, and other waste from both 10,000-gallon separators, draining them completely.

3.3 Cleaning Procedures

The contractor shall thoroughly wash and clean the interior of the separators.

All secondary wash water generated during this process must be captured, containerized, and managed in accordance with Section 3.2.

While the separators are empty and clean, the contractor shall conduct a comprehensive inspection of the structural integrity and functionality of all system components.

The contractor shall provide a detailed report of the items inspected.

3.4 System Restoration

Following the washing and inspection phase, the contractor shall refill the separators with clear water to re-establish the proper operational seal, ensuring no residue is flushed into the discharge line during restart. The Government will provide access to an on-site water source at no cost to the Contractor for the purpose of refilling the OWS units after cleaning. The Contractor shall be responsible for providing all necessary hoses, fittings, and conveyances to transport water from the source to the OWS.
